Numerical evaluation of temperature fields and residual stresses in butt weld joints and comparison with experimental measurements

Autor: Raffaele Sepe, Alessandro De Luca, Enrico Armentani, Alessandro Greco

This paper presents a novel numerical model, based on the Finite Element (FE) method, for the simulation of a welding process aimed to make a two-passes V-groove butt joint. Specifically, a particular attention has been paid on the prediction of the

CDW aluminium joints welding and optimisation with NDT/mechanical testing

Autor: Marta De Giorgi, Francesco W. Panella, A. Carofalo, V. Dattoma, Fania Palano

This work investigates the possibility to apply the improved hybrid capacitor discharge welding (CDW) process, based on projection welding principles, to aluminium alloy Al 5754. The CDW process is an electrical resistance welding technology, realise

Compressive residual stress in hard coatings can improve adhesion and in-service toughness, since they can inhibit crack nucleation and propagation. However, the role of through thickness residual stress profile is not fully understood. This is becau

Hybrid technique to assess the fatigue performance of multiple cracked FSW joints

Autor: Roberto Guglielmo Citarella, Pierpaolo Carlone, R. Sepe, Marcello Antonio Lepore

Publikováno v: Engineering Fracture Mechanics. 162:38-50

In this paper a numerical–experimental procedure useful to numerically assess the fatigue performance of friction stir welded aluminium joints is presented. The impact of manufacturing residual stresses on crack propagation in the joint driven by a

Residual stresses play a crucial role in determining material properties and behaviour, in terms of structural integrity under monotonic and cyclic loading, and for functional performance, in terms of capacitance, conductivity, band gap, and other ch
